Here is the actual code which i will be using, the move() method is where i need to carry ou this task. An idea where to start would be great. Havent used the % either, does it mean 2/3 remainder 2 or 3/2 remainder 1. Not really sure, the output is not illegal move but know move will take place. Thanks for the help.
When a legal move is made the square switch color.
